I bought several packs of these windscreens to use as disposable windscreens during the COVID-19 pandemic. As the sound engineer, I give each singer a new one (still in the package - they come individually wrapped, which is nice) and tell them to keep them or I'll throw them away after the show. I'm not sure if that helps or not, but it won't hurt. The windshield works as it should and is reasonably priced for a one-time use. I can't say anything about durability.
